I just got this 1993 Integra and it will crank but not start, it almost started once but it automatically died a second later, has new ecu and distributor. Grounds are all in correct loc.

What i think the problem is::
I have continuity from Positve battery lead to Thermostat Ground. WTF!?!?!
Is it just me or is this fucked up?

How do i trace what is shorting out into the ground?
What is the most efficient and easiest way of finding a short?
It has a Solid check engine light also , that i can't get rid off.

 

did you pull the code for the CEL?

 

Yea ecu is jumped . SOlid cel, Im guessing because something is shorting out. Must be ecu wiring related.

But how do i know like what to look for, what could cause problems,

 

expletive, no wonder it was 500 bux. haha.

 

1 hour 34 seconds bump

 

check for fuel/spark

 

The solid cel could mean that the fuel system isn't pressurizing, aka main fuel relay MFR. Doesn't a bad ECU also throw a solid cel?

 

My fuel pump primes nicely, My fuel pressure is 40 psi.
It starts but dies instanly, distributor is new, new plugs, wires etc.

yo check this

When the car was running for 1 minute ( surprisingly) i checked voltage at injectors all had 12.5 volts except for number 1 injector, I then checked injector solenoid by running wires to battery from injector , and it clicked strong, I then checked Continuity and it was ok.

THis is def wiring related.
I just want to know how to find a short, Will the A plug on the ecu most likely be the culprit? Most ecu power and grounds are on plug A.

cant be bad ecu, worked on friends car, i bought two just incase, p28 and p08

 

Car starts and dies instantly now. Whyyyyyyy
Continuity from positive terminal to body ground. cant be goood right?
